when x number units are sold, the price of each unit (in dollars)is given by P = -x/2 + 75, find the unit price when the quantities are sold: 2,7,9,11

  • Algebra -

    Just plug in the assumed value of x and compute -x/2 + 75.

    When x = 2, P = -2/2 + 75 = $74.
    When x=11, P = -11/2 + 75 = $69.50
